first of all I want to thank you for developing PHD Guiding! It is a great software and the fact that it is open source helped me a lot.
I am a PhD student in the field of Machine Learning and learning periodic error curves in an "automagic" fashion is one of my research projects. I use PHD Guiding for the hardware interaction and implemented everything else in Matlab. Now the time has come where we would like to have a working implementation of my research code inside of the guiding software. Since it is much easier to extend a software for someone who is already familiar with the source code, I would be great if one of you would be interested in implementing my method. Of course, we don't expect you to implement our stuff for free. My institute is willing to pay for the development.
